This is the common definition for bioindicator, other definitions can be discussed in the article

Notes

Bioindicators are necessary for certain hydrophobic pollutants, because these compounds tend to be adsorbed by biota soon after entering the ecosystem. This makes that the concentrations in the water might not reflect the contamination in the biota.
